Organizers said the volunteers, in teams of three people, will be going door-to-door asking to check batteries, replacing them with 10 year lithium batteries, installing new dual-sensor smoke alarms and sharing fire prevention and safety information.

Registration starts at 8 a.m. at the Polk County River Place offices at 2309 Euclid Ave. The effort is expected to run until 3:30 p.m.
